Abstract

Aquatic environmental pollution due to petroleum waste can cause disruption to the environment and damaging of flora and fauna. It has been reported that petroleum contaminatin occurs in the Bengawan Solo river, East Java Province. Liquid hydrocarbon waste pollution can be remediate through various processes, one of them is biodegradation. Biodegradation a part of bioremediation, is the process by which organic substances are decomposed by microorganisms into simpler substances such as carbon dioxide, water and ammonia. Bioremediation has minor side effects compare to other methods because it’s more effective, efficient, economical and eco-friendly through biological process. This study aims to identify bacteria for liquid hydrocarbon degradation from the rivers in Wonocolo Village, Bojonegoro District and to determine maximum percentage of inoculum to produce the highest efficiency of liquid hydrocarbons degradation. Based on phenotypic characters, the selected bacteria was identified as a genus of Moraxella. Its bacterium with a concentration of 2 % can reduce hydrocarbons to a maximum of 0.67 % per hour at the exponential phase growth.

Abstract

Lactobacillus has long been known to reconstruct the microbiome of the urogenital organs of healthy people. However, changes in lactobacillus abundance are known occurring in urogenital tract infections (UTI) patients. It is also known that there are Lactobacillus species that have specific genomic characteristics and nutritional requirements that cause them to turn into pathogens. Understanding population characteristics and taxa composition that reconstruct urine microbiome is very important for the diagnosis and treatment of urogenital infections. This review provides an update information of metagenomic sequencing to identify the urinary microbiome profile and the role of lactobacilli in healthy and UTI patients.

Abstract

The objective of this study was to investigate the diversity of bacteria in the rhizosphere of Acacia grow in the forest and different ages of revegetated land and non-rhizospheric bacteria from active tin mining soil on Bangka Island with a metagenomic approach and to investigate its relationship with physicochemical properties of the soil and its metal content. 17 species/genera were found in the four fields, and Bradyrhizobium is the dominant genus. Bacterial communities of the forest (more than 5 years in revegetated post-tin mining land containing C, N, P, and Fe) are Paraburkholderia sp., Bacillus sp., Candidatus-Xiphinematobacter, and Bacterium enrichment. The physicochemical properties of soil from less than 5 years of revegetated contain Cu, Cr, and Mo, and the dominant species in this soil were Bulkhorderia sp., Bacillus lehensis, B. fordii, B. thermolactis, Chloroflexi bacterium, and Thermonosporaceae bacterium. The physicochemical properties of soil from the mining were dominated by Cd and Ni, and the dominant species in this soil were Sinomonas atrocyanea.
